STEVAL-ISA071V2, 4W, Non-Isolated, Wide Input-Voltage Range SMPS Demonstration Board based on VIPer16
STEVAL-ISA071V2, Demonstration Board is a non-insulated SMPS capable of delivering 4W output over a wide input voltage range and is designed for a mains application requiring -5V and +7V, referred to neutral. The basic concepts used in this design can also be applied for higher power outputs or different voltage ranges. The SMPS generates outputs of 5V and 12V, referred to the output marked -5V. The 5V output is dedicated to supplying an MCU. This configuration allows the use of the MCU to directly drive a Triac (referred to neutral). The 12V output is used to supply additional circuits (relays, OA, etc.)
